BoundaryPatch from Sketch3D with SketchEntities3D - API C# or VB.NET

[florian_wenzel]

Hi,

Inventor 2024

API Visual Studio C#

i try to create a Surface with BoundaryPatch using BoundaryPatchFeature.

Is there a way, to Create a Path, GuideRail or Profiles3D ?

So the problem is, that if i Create Curves with API, and i dont Connect the Points, then this is not a Profile3D, 

and im not able to Create Profile.AddClosed()

a Surface with BoundaryPatch Feature.

Is there a WorkAround, or any Solution?

I was try with Path,  CreatePath or CreateSpecifiedPath.

Or with only One SketchEntity, with each etc..

How to Use the GuideRail with BoundaryPatch Feature?

Example Code: 

        PartDocument oPartDoc = (PartDocument)Globals.g_inventorApplication.ActiveDocument;
            PartComponentDefinition oCompDef = oPartDoc.ComponentDefinition;
            TransientGeometry oTG = Globals.g_inventorApplication.TransientGeometry;
            TransientObjects oTO = Globals.g_inventorApplication.TransientObjects;
            TransientBRep oBRep = Globals.g_inventorApplication.TransientBRep;
            MeasureTools oMeasureTools = Globals.g_inventorApplication.MeasureTools;

            Sketch3D oSketch3D = oCompDef.Sketches3D[1];

            ObjectCollection oObjColl = oTO.CreateObjectCollection();

            foreach (SketchEntity3D oSketchEntity3D in oSketch3D.SketchEntities3D)
            {
                if (oSketchEntity3D.Type != ObjectTypeEnum.kSketchPoint3DObject)
                {
                    //Path oPathGuide = oCompDef.Features.CreatePath(oSketchEntity3D);

                    oObjColl.Add(oSketchEntity3D);
                }
            }

            Path oPathGuide = oCompDef.Features.CreateSpecifiedPath(oObjColl);

            ObjectCollection oObjColl2 = oTO.CreateObjectCollection();
            oObjColl2.Add(oPathGuide);
         

            BoundaryPatchDefinition oBoudaryPatchDef = oCompDef.Features.BoundaryPatchFeatures.CreateBoundaryPatchDefinition();
            oBoudaryPatchDef.GuideRails.Add(oObjColl2);
            BoundaryPatchFeature oBoundaryPatch = oCompDef.Features.BoundaryPatchFeatures.Add(oBoudaryPatchDef);

Thanks For any Suggestion
